Ronsford Beaton gave a glimpse of his startling pace at Under-19 World Cup in 2012, where he picked up eight wickets in five matches. He broke through the first-class ranks for Guyana in 2011, but it wasn't until 2012-13 that he was seen as a fast bowler meant for higher honours. He took 16 wickets in six matches in the Regional four-day competition, complemented it with seven wickets in five matches in the subsequent T20 tournament and earned a deal with the CPL franchise Guyana Amazon Warriors. He has since moved to Trinbago Knight Riders.
Beaton, a product of WICB's High Performance centre, impressed for West Indies A during the one-day leg of the tour to Sri Lanka in November 2016 by picking up seven wickets in three games. In February, he was selected to play for WICB XI against the visiting England side in a warm-up fixture. Three months later, he received a maiden West Indies call-up for the T20I series against Afghanistan at home.
